WILLIAM H. SCOVILL, OF CHICAGO, ILLINOIS.

I SHEET-JOGGER FOR PRINTING-PRESSES.

Application filed July 20, 1916.

To all whom it may concern:

Be it known that I, WILLIAM H. SoovrLn, a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Sheet-Joggers for Printing-Presses, of which the following is a specification.

This invention relates to improvements in sheet j oggers for printing presses.

The main objects of this invention are:

First, to provide an improved sheet jogger for printing presses adapted for use as an attachment for various types of machines now in use.

Second, to provide an improved sheet jogger for printing presses which may be quickly put into operative position and adjusted to the machine.

Third, to provide an improved sheet jogger adapted when used in pairs to jog or square up the sheets on all sides.

Fourth, to provide an improved sheet jogger which is simple and economical and at the same time durable in use.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow. 7

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail plan view of the table of a printing press with one of my improved sheet joggers in operative position thereon.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the piling table of a printing press and 2 a reciprocating part of the sheet delivery mechanism thereof. On this reciprocating part 2, I mount a bracket 3 having an actuating roller I for my improved sheet jogger.

My improved sheet jogger comprises a frame preferably rectangular and formed of sheet metal. Within this frame and transversely thereof are ways 6 for the slides 7 of the jogger blade 8, this jogger blade being thus supported to reciprocate at the front of the frame to engage the edges of the sheets as they are piled on the table by the delivery mechanism jogging or squaring them up.

The frame is provided with a series of teeth 9 on its under side adapted to engage the table. These teeth may be in the form of a rubber pad with corrugations, the 0bject being to hold the frame in its adjusted position on the table without necessity of attaching or clamping the same thereto.

The frame is provided with a forwardly projecting plate over which the jogger blade 8 reciprocates, the jogger plate being recessed at 11 to receive the blade, see Fig.

' plate as the sheet is delivered.

XIII. This plate 10 is adapted to support the sheets so that all the first sheets are efiectively engaged by the jogger blade.

The jogger blade slides 7 are provided with racks 12 on their upper sides and these racks are engaged by the pinions 13 carried by the shaft 13 arranged longitudinally of the frame and having bearings in the end thereof. This shaft 13 is actuated by the racks 1 1 carried by the actuating bar 15 which is provided with a cam bar 16, the cam bar being adjustably mounted on the actuating bar. The racks 1 1 are mounted to reciprocate in suitable vertical ways 17 supported by the frame, as best shown in Figs. II and V. Stops 18 are provided to limit the upward stroke of the racks 14. hen the racks 1 1 are forced downwardly by the actuation of the actuating bar 15, as through its cam bar 16 and actuating roller 1, the rock shaft 13 is rotated and pinions 18 thereon coacting with racks 12 retract the jogger plate 8. When the actuating bar is released by the passing of the roller from the cam bar, the springs 19 actuate the jogger blade on its outstroke. These springs 19 are connected at one end to the front part of the frame and at their other ends to a rod 20 extending between the slides 7 (see Figs. II, III and VIII).

To provide means for adjusting the cam bar 16 to machines of different size, the cam bar is adjustably mounted on the actuating bar 15, the cam bar being provided with rods 21 telescoping with the tubular members 22 on the actuating bar 15. These tubular members are arranged through the supporting brackets 23 for the slide bearings 17 of the racks 1-1 (see Figs. II and IV). The rods 21 are secured to the actuating bar in their adjusted position by the set screws 24:.

With the parts thus arranged, the reciprocation of the sheet delivery member 2 actuates the actuating bar and through the connections described, retracts the jogger On the return movement of the sheet delivery member 2, the actuating bar 15 is released and the jogger plate .is actuated by its springs to jog up the sheets.

To jog up the ends of the sheets, I provide end jogging blades 25 which are slidably mounted on the bracket extensions 26 of the frame, the extensions 26 being adjustably mounted on. brackets 27 mounted at the ends of the main frame. These bracket member extensions have registering slots 28 and 29, clamping screws 30 being provided to hold theextensions in their ad justed position on the brackets.

The end jogging plates 25 are carried by slides 31 reciprocating in the slots 29 (see Figs. IX and XI). The end jogger blades are actuated by the pitman 32 which has a telescoping slide 32 adjustably secured by the screw 2. The slides 31 are secured to the telescoping slides 32 by the pins 53 carried by the coupling 3a on the telescoping slide 32, this coupling being adj ustably secured upon the telescoping slide by the set screws The inner ends of the pitman are connected to the crank members 36 on the shafts 37 and connected by the links 88 to the actuating bar 15. Thus when the actuating bar is actuatet, the end jogger blades are carried outwardly or to their retracted positions simultaneously with the retracting of the side jogger blades and when the actuating bar is released, the end jogger blades are actuated by means of springs 19 and the connections described. The device being adapted to be adjustably positioned on the table or tray may be adjusted to the proper position for jogging up the side edges of the sheets, while the end jogger blades may be readily adjusted to the dimensions of the sheets for jogging up the ends thereof, the term side and ends being used as relative terms in relation to the press proper.

In practice, the devices are used in pairs, being positioned oppositely. The cam bar 16 is provided with cams ateach end so that the device may be positionedon either side. I have used the term table in its broad sense and'have in mind that paper is frequently piled on trays or the like.

My improved sheet jogger is adapted for use on the table proper or on trays or otherwise, as may be desired. My improved sheet jogging machine is adapted to be used. as an attachment for various printing machines now in use, little change or addition being required to adapt the same thereto.

I have not attempted to illustrate or describe various modifications which I contemplate as being desirable under certain conditions, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as circumstances may require.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
